Sony brings over a million Google Books to the Reader

Cool move by Sony to bolster the number of titles in its Reader ebook store -- it's linked up with Google to provide over a million free public domain works from Google Books, just like those fun folks at Barnes and Noble. The books are in the EPUB format and will work with the PRS-505 or the PRS-700 in the US only for now -- different countries have different copyright terms, so we'd imagine the lawyers are busy sorting it all out. Sure, none of this will do much to shake the Kindle's market- and mindshare, but at least Sony won't be deleting this stuff off your device without your permission, right?
